Operate effectively with senior architects and technical fellows, integrating across disciplines and navigating a fast moving environment with minimal oversight.
Leverage subject matter expertise in system of systems architecture, inter CSCI interfaces, software requirements, and SW/HW integration to drive technical clarity across a broad array of potential sensor and effector integrations.
Utilize advanced modeling tools (Cameo/EA), MOSA standards, and multi discipline agile leadership experience to communicate technical decisions across engineering teams, customers, and vendors, and to support major design reviews.
Architect, implement, test, and debug embedded real‑time software in heterogeneous hardware, firmware, and software environments.
Participate in major design reviews, including PDR and CDR.
Mentor less experienced engineers.
Occasional business travel may be required, up to 5%.
Onsite role in McKinney, Texas, with local residency or relocation required.

Qualifications You Must Have

Typically requires a degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 8 years of prior relevant engineering experience.
Experience with software architecture for large scale and complex system‑of‑systems, subsystem interface design, and software integration and test.
Experience with engineering and modeling tools (Cameo or Enterprise Architect, MS Visio) and familiarity with MOSA standards (OMS, AMS‑GRA, A-GRA).
Experience developing, testing, and integrating real-time software applications using C++ or related software languages and Linux, VxWorks, or other real-time operating systems.
Product-domain experience in at least one of the following areas:
- RF or EO/IR Sensors
- Electronic Warfare
- Effectors
- Communications
- Multi-domain Mission Systems
The ability to obtain and maintain a U.S. government issued security clearance is required. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.

Ability to develop and present complex technical material at design reviews such as PDR and CDR.
Ability to work effectively in fast-paced, dynamically changing environments.
Proactive problem-solving and strong ownership mindset.
Experience working in system integration lab (SIL) environments with physical hardware including test benches and simulators.
Experience with Agile Scrum development practices.
Hands-on experience with Git for version control and GitLab or Artifactory for repository management.
Familiarity with DevSecOps pipelines including static analysis, automated build and test, CI/CD, and test-driven development.
Active and transferable U.S. government issued Secret security clearance with special program access.
